1,540,7 UNITED STATES PATENT T'oFFr/c sPLIoING NEEDLE AND TUCKER,

Application filed m 18, 1924.. Serial No. 726,763.

To all whom it may concern:

Be it known that I, DAVID II. MGCRAY, a citizen of theUnited States, residing at Tulsa, in the county of Tulsa and State of Oklahoma, have invented certain new and useful Improvements in Splicing Needles and Tucker's; and I dodeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to.

make and use the same, reference being had I to the accompanying drawings, and toythe figures of reference marked thereon, which form a part of this specification.

This invention relates-to a splicing nee dle and tucker, particularly designed for making a splice in a wire cable. Wire cables such as are used in the. oil well'indus try must be spliced from time to time and the splice must of necessity be neatly made -Fig. 2 is a perspective view of the par tiailly spliced cable showing the spliced needle or marlin spike and the tucker in position to complete the splice.

Fig. 3 is a cross sectional view through the tucker, the tucking needle being shown in edge view, and

Fig. 4 is a perspective view ofone end of a cable.

When the cable 1 has its ends spliced together, the ends of the two strands 2 and 3 are loose so a needle or marlin spike 4 is in serted, the marlin spike or needle having an enlarged portion 5-near its end with a cut ting edge which will cut the fibre core 6,

then the tucker blade 7 is inserted through several of the strands as shown in Fig. 2. The helper then reaches in Witha pair of pliers 8 or similar tooland grasps the core 6 so that it can be pulled out of the cable to make room for one of the strands for example2 which may now be tucked in by a tucker bar .comprisinga lever 9 pivoted on inecting the stop to the bar.

the sleeve 10 adjustably mounted on the tucker blade 7 and'held'inany adjusted position by the set screw 11. The pivot 12 secures the barg9 to the sleeve 10.

One end of the tucker bar is provided with a handle 13. The other end has a half round groove 14- receiving the loose strand so that item be pushed into the space previously occupied by the core 6. The cable is I held from turning during this time by the marlin spike or needle 4, the bar 9 carries a chain or other flexible connection 15 to which is secured a stop pin 16 passing through an opening 17 in theblade 7 so that as the tucker bar exerts pressure against the strand 1 2, the cable will be held against longitudinal movementon the blade 7 by the stop pin 16.

WVhen one strand'is tucked in the operation is repeated for the other strand, therefore a neat eifective blind or invisible splice tucked in the center of the cable so that ha 'ismade with the free ends ofthe splice bility of their catching onany projection will be entirely eliminated. The inarlin spike 4 and the tucker blade 7 is provided with T-heads 19 and20 which become effective in hammering the cable into shape after the splice is-completed. Of course it is understood that after a sufficient length of thecore has been removed from thecenter of the cable, its extended end will be severed close to the cable and theend of the core tucked intothe center of the cable so that it will be entirely enclosed between the cable strands. o

What I claim and tors-Patent is Y a 1. Meansfor splicing'a cable comprising a blade, a tucker rod adjust'ably mounted on the blade and a cable stop on the blade.

the cable stop being removably secured to i the bladeand means for permanently con- 3. In a device of the class described, cable'engaglng blade, a sleeve on said blade, means forbinding the sleeve to the blade,a bar pivoted on the sleeve, a stop pin for engaging an opening in the blade and a flexi-.

5. In a device of the class described C0111- prising a blade having a hammer handle on one end and a perforation onthe other, an

adjustable sleeve on the blade, a tucker bar pivoted on the sleeve, 2 pin for engaging the perforation and a "flexible connection be- 10 tween the pin and the bar.

In testnnony whereof I aflix my signature.
